Question
I'm using MBProgress HUD and I don't know what is the problem.
I have a UIButton
that shows the HUD.
This is my code:
- (void)showHUD:(id)sender {
HUD = [[MBProgressHUD alloc] initWithView:self.view];
HUD.mode = MBProgressHUDModeCustomView;
[self.view addSubview:HUD];
HUD.delegate = self;
HUD.labelText = @"No Internet Connection...";
HUD.opacity = 0.7;
HUD.customView =
[[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image.png"]];
[HUD showWhileExecuting:@selector(hudWasHidden)
onTarget:self
withObject:nil
animated:YES];
}
- (void)hudWasHidden {
float progress = 0.0f;
while (progress < 1.0f) {
progress += 0.01f;
HUD.progress = progress;
usleep(50000);
}
}
Here is the Console log:

My app always crashes when clicking the UIButton
.
Thanks
Solution
This is a common crash in Cocoa code: "unrecognized selector" is very explicit in this case. MBProgressHUD doesn't have a customView
property, and attempting to set it is causing the crash. The setCustomView
is the implicit selector (method) being called here, and Objective-C will crash when a called method isn't there.
Not sure what to tell you about how to accomplish what you're trying to do.
